In The Beginning
We’re in a bad place...
Business Need: “We need a mobile web presence”
Developers: “Sure, we can do that”
Mistake: “Rewrite Everything!”
Business Need: Mobile First http://m.komplett.no
Project K2

K2 is a Deadly Mountain
Our project did not survive
Learning: “Don’t Rewrite Everything!”
It was a dark time…
They Still Trust Us!
New business-domains.
Great big heap of code.
Can we do this?
but...
Do We Trust Us?
Mistake: “Just Add Developers”
Before Scaling
Spotify Model
The Minion-project
Growing Pains
Komplett As Services
Our architectural vision
A landscape of small Services
Versioning is naming
Consistent deployment
Splitting out services from the monolith
Creating A New Service
Learning: “Services must be cheap”
OK, How Do We Do That?
How can we get all this done?
How do we push more features through the pipeline?
Komplett Model
'
How we communicate
Learning: “Organisation matters”
Mistake: “Just split it into services”
OK, How Do We Do That?
How do we keep it running?
Caching
Performance tests
Independently scaling services
Health-checks and monitoring
Central logging service
Learning: “Services are differenterer”
Where Do We Go From Here?
Fully mandated squads?
More microservices?
Public APIs
More business-areas!
Summary
Scaling is hard
Culture is Crucial
Embrace and learn from failures
We intend to keep failing and sharing as we go.
